dmesg

Graphics: ATI RV620/M82 [Mobility Radeon HD 3450/3470]

https://bugs.freedesktop.org/show_bug.cgi?id=66963 was fixed but here comes new
problem. When booting into X(KDE splash screen), it seemed to freeze(even after
a cold reset), but I managed to switch to tty and get the dmesg. Xorg log is
fine. In the end I have to shutdown.
This situation seems to be more often than normal booting.
